Answer 1

It's a reference error.

The slider is in group 1 of group 1. When using GUI scripting it's also recommended to wait for particular UI elements in case there are time-critical changes.

activate application "Instruments"

tell application "System Events"
    tell process "Instruments"
        keystroke "," using command down --Instruments menubar -> Preferences
        tell window 1
            click button "CPUs" of toolbar 1
            tell group 1 of group 1
                repeat until exists slider 1
                    delay 0.2
                end repeat
                set value of slider 1 to 2
            end tell
        end tell
    end tell
end tell
